Hi Howard, Jeff, Tim, Dave, et al,

Sorry, but the VX-8R is NOT full duplex. It is true - there are no 
current-production full-duplex HTs out there. The Alinco USA folks did say 
that they would have a full-duplex DJ-G7 HT at Dayton. It is currently 
offered in Japan. Another comment that surfaced was that the HT would be 
available in the US around June. If it is coming to the US sometime this 
year, I will certainly be interested. It is a tri-band unit with 2M, 70cm 
and 23cm. That sounds like fun! Power output on 23cm is lower than 2M and 
70cm, but a gain antenna should fix that...

I have a pair of Alinco DJ-580T HTs. I bought my first one new in 1992, did 
some appropriate mods, and started using it for satellite contacts. It still 
looks and works great even after a number of cruises and other portable 
operations. I had both of them with me on a February cruise and got a chance 
to discover that they are both in fully-operational condition with 
reasonably good sensitivity on 70cm receive. Hopefully the DJ-G7 will 
perform as well or better. My other full-duplex HTs include the Kenwood 
TH-D7 and the Yaesu FT-530.

GL! Andy W5ACM
